To a whom it may concern.-

Be it known that we, \VILLIAM E. DAVIS and SAMUEL A/MILLER, citizens ofthe United States, residing at Centralia, in the county of Columbia andState of Pennsylvania, have invented certain new and useful Improvementsin a Combination Hitching-Post and Cut-Off Plug; and we do declarethefollowin g to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appcrtains tomake and use the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification.

This invention relates to certain new and useful improvements in acombination hitching-post and cut-off rod designed to be connected to astopcock of a water-main, whereby water may be turned off from the mainduring the coldest weather without any hindrance from frost displacingthe means for turning the valve in the pipe.

Ourinvention consist-s, further, in the provision of a two-part postwhich is hollow, one portion being permanently held down over thewater-main, while the upper portion is allowed to rise or to heave withthe frozen ground without in anyway rendering it impossible to turn offthe water through the medium of the valve-rod carried within the hollowextensible post.

A further aim of the invention relates to the forming of a combinationpost and frost-lift within which is located a rod connected to astop-cock, the various parts being locked up, so as to render itimpossible to turn off the water from the main without first removing aring-cap to the post, which is held in a locked relation by means of apin passed through adjacent edges of the cap and a collar on the post.

To these ends and to such others as the invention may pertain the sameconsists, further, in the novel construction, combination, andadaptation of the parts, as will be hereinafter more fully described,and then specifically defined in the appended claim.

We clearly illustrate our invention in the accompanying drawings, which,with the letters of reference marked thereon, form apart of thisspecification, and in which drawings similar letters of referenceindicate like parts throughout the several views, in which- Fign re 1 isa side elevation of our invention. Fig. 2 is a central vertical section.Figs. 3 and 4 are detail views.

Reference now being had to the details of the drawings by letter, Adesignates the lower sectional portion of the post, recessed at itslower end at a, and is hollow, designed to receive the cylindricalportion 13.

C is a water-main seated in the recesses (t at the lower end of thepost-section A, and E is a turning plug to which is connected the rod F,which passes up through the inner hollow post B, and is squared at itsupper end at f, over which squared end a wrench or key may be placedwhen it is desired to turn off the water in the main.

To the upper end of the post-section B is carried the screw-threaded capH, which is prevented from being unscrewed by the bolt J being screwedin to anaperturej in the collar K of the post-section B, the flange J ofthe said bolt being designed to be seated in registering recesses in thescrew-threaded cap and the collar of the pipe-section. On the oppositeside of the post is a screw-threaded pin N, carrying a ring at its outerend, the said pin having a recess in which the screwthreaded cap isadapted to rest to prevent the pin being removed.

M is a yoke carrying the tightening-screws m and is designed to be heldto the post-section B to limit the distance at which it is desired tolower the said pipe-section into the stationary portion A, and to servealso as a means for preventing the post turning when it is desired tounscrew the cap.

It will be observed that an important feature of our invention residesin the provision of the frost-1iftingfeature of the invention, whereinthe sect-ion B is allowed to raise from the effects of the frost heavingthe ground, while the bottom or section A remains unmoved.

Having thus described our invention, what we claim to be new, and desireto secure by In testimony whereof we affix our signa- Letters Patent, istures in presence of two witnesses.
